ANTIGLARE DEVICE FOR HEADLIGHTS.

Application filed December 13, 1926. Serial No. 154,435.

My invention relates to a new and useful improvement in an antiglaredevice for headlights adapted for use on vehicles of various kinds, andhas for its object the. provision of a device whereby the direction oftravel of the rays of light may be controlled and the glaring effects ofthe headlight eliminated.

Another object of the invention is the provision of a normally tiltedsupporting member having a plurality of deflecting members mountedtherein at an inclination thereto so that normally the rays of lightwill be directed in a horizontal path and may be directed at adownwardly inclined direction at will.

Another object of the invention is the. provision of a device of thiskind which will be simple in structure, economical of manufacture,-durable and efiicient in use, and easily and quickly operated.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of partshereinafter .de-' scribed and claimed.

The invention will be best understood by a reference to the accompanyingdrawings which form a part of this specification and in which Fig. 1 isa diagrammatic view of the invention, illustrating the operation of theinvention. 7

Fig. 2 is a central vertical sectional view of the invention applied toa vehicle headlight.

Fig. 3 is a front elevational view of the headlight with the inventionattached. 7

Fig. 4 is asectional view taken on substantially line 4-4 of Fig. 2.

The invention is illustrated as mounted on a headlight having an outershell 7 and a reflector 8 the light bulb 9 being mounted inwardly of thereflector. I have provided a retaining ring 10 which is adapted formount-. ing over the upper edge of the headlight shell 7 so as tosupport the lens 11 in position. Projecting inwardly from the shell 10at its forward side are lugs 12 and 13, between which is pivotallymounted a lug 14 which is carried by the annular member 15. Extendingchordally of the annular member 15 are deflecting members 16, thesemembers being positioned between cleats 17 and 18 which are mounted onthe inner surface of the annular member 15. As shown in Fig. 2, theseshutter forming members 16 do not lie i11 lanes parallel to the axis ofthe annular mem 15, but are slightly inclined thereto, so that when theannular member 15 is at an inclination, as shown in Fig. 2, the shutterforming members 16 will lie in planes horizontal or parallel to the axisof the light bulb 9. It will also be noted that the shutter formingmembers beginning from the top and proceeding to the bottom of'theannular member 15 are stepped rearwardly of each other, this location ofthe shutter forming members in this device being quite estential to theeffective operation of the device. These deflecting members 16 may be,if desired, made from glass, in which case the upper surface thereofshould be frosted or rendered non-transparent, these shutter formingmembers being so constructed that light striking the under surfacethereof will be reflected therefrom, while lightv striking the uppersurface thereof will not be reflected. Formed in the rin 10 at its baseis a slot 19, through which pro ects the tree 20 of a yoke, the arms 21and 22 thereof being formed arcuat'e, and pivotally connected, adjacenttheir ends, to the ring 15. Projecting downwardly from the lower side ofthe ring 10 is a lug 23 upon which is pivotal- 1y mounted, intermediateits ends, a link 24 which is pivotally connected at one end to the tree20, this tree 20 having a slot 25 formed therein to facilitate theconnection. Connected to the opposite end of the link 24 is a rod 26which may extend to any convenient position accessible to the operator'of the vehicle so that swinging of the ring 15 on its pivot may beeffected at will. Projecting inwardly from the ring 10 is a lug. 27,at-- tached to which is one end of a spring 28; the other end beingattached to the tree 20 $013 to normall retain the ring 15 in theposition shown in ull lines in Fig. 2. In this osition the light ra semanating from the. ight bulb 9 will be directed forwardly from theheadlight in parallel planes and the glare which is frequentlyencountered upon approachin a vehicle headlight will be eliminated. endesired to cast the rays -of light downwardly the ring 15 may be movedto the position shown in dotted lines in Fig. 2.

It will be noted in Fig. 3 that the appearance of the headlight from theforward side there of is not altered from the ordinary ap-- ,in whichthe rays 27 of light are deflected downwardly, the point 28 in icatingthe location of a driver of an approaching vehicle and While I haveillustrated and described the preferred form of construction, I do notwish to limit myself to the precise form of structure shown, but desireto avail myself of such variatlons and modifications as may come withinthe scope of the appended claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1.' A device of the class described adapted for use with a vehicleheadlight having an outer shell, comprising: an annular member mountedon. the forward side of said outer shell; a lug projecting inwardly fromthe upper side of said annular member; a ring hingedly mounted on saidlug; a plurality of chordally extended planar deflecting members mountedon said ring at a rearward, downward inclination to its axis, said ringbeing normally in tilted positionrelatively to the vertical, saiddeflecting members lying normally in a horizontal plane; and means forfurther tilting said ring for inclining said deflecting membersforwardly downwardly of said headlight; and resilient means for normallyretaining said ring in its first position of tilt.

2. A devce of the class described adapted for use with a vehicleheadlight having an outer shell, comprising: an annular member mountedon said outer shell at its forward side; a ring hingedly mounted at itsupper side to the inner surface of said annular mem her; a plurality ofchordally extended deflect ing members mounted on said ring and inclinedto the axis thereof, said ringbeing normally tilted from the verticalfor retaining said deflecting. members in horizontal planes; a lugprojecting from the periphery of said annular member at its lower side;a link pivot'ally mounted intermediate its ends on said lug; a yoke, thearms thereof embracing said ring and being pivotally attached thereto,the end of the tree of said yoke being pivotally connected to one end ofsaid link; and means for rocking said link on its pivot for varying thedegree of tilt of said ring relatively to the vertical. 7

3; A device of the class described adapted for use with a vehicleheadlight having an outer shell, comprising: an .annular member Imounted on said outer shell at its forward side, a ring hingedly mountedat its upper side to the inner surface of said annular member, aplurality of chordally extended deflecting members mounted on said ringand inclined to the axis thereof, downwardly at their rear edges, saidringbeing normally tilted from the vertical for retaining saiddeflecting members inhorizontal planes; alug projecting from theperiphery of said annular member at its lower side; a link pivotally vmounted intermediateits ends on said lug; a yoke, the arms thereofembracing said ring and being pivotally attached thereto, the end FREDGROSIUS.
